FIELD OF NOTES

INVOLUTION-EVOLUTION AXIS

These fields were constructed by numbering the coordinate axis only as far as the ratios of each note... (8:9 equals RE)... Where each number met... the appropriate notes were placed... One axis must be an involution axis running toward the juncture of the axis... One axis must be an evolution axis going outward... Therefore the numbering must be reversed along one of the axis... (See illustration P-18)
